Chris Tillman will start Wednesday and Tyler Wilson will start Thursday for Baltimore. The Nationals have not announced their starters after Tuesday.

The Orioles began the day 5 1/2 games out of the second AL wild-card spot. The Nationals trailed the NL East-leading New York Mets by six games.

TRAINER'S ROOM

Orioles: CF Adam Jones was out of Monday's lineup with back spasms, manager Buck Showalter said, even though Jones insisted he was dealing only with recurring soreness. ''I'm human, though,'' Jones said. ''Let me have a day off without it being a story. It's not a story.'' Jones has played 159 or more games in each of the past three seasons, but has dealt with shoulder and ankle issues this year. . RHP Miguel Gonzalez (shoulder) expects to throw a simulated game on Wednesday and hopes to make two starts before the close of the season.
